Some cataracts grow larger or denser over time, causing severe vision changes. Severe cataracts can cause loss of independence for older adults as decreased vision may affect driving, working, reading, or hobbies. While cataracts can cause blindness, this is rare. Surgery is usually done before a cataract progresses far enough to cause blindness. A rare type of cataract can lead to glaucoma.
Finally, although macular degeneration, mainly age-related, was estimated to be the cause of 7% of blindness and 3% visual impairment worldwide, cataract and undercorrection of refractive error represented more than 50% of all cases.
